CesiumAstro just secured $270M in Series C equity and stacked it on top of a $200M EXIM and J.P. Morgan financing package. That is not a casual capital raise. That is a signal flare visible from low Earth orbit.
Shey Sabripour built this company in 2017 with 30 years of aerospace scar tissue, including 24 years at Lockheed Martin Space Systems. You do not survive that long in defense unless you understand frequency, friction, and federal budgets. Now Shey Sabripour is steering a vertically integrated machine out of Austin that designs, builds, and tests software-defined active phased array systems for commercial and national security missions. Payloads, radios, terminals, satellites. If it talks in space, CesiumAstro wants to power the conversation.
Ken Smith, now CFO, helped orchestrate a capital stack that reads like a geopolitics syllabus. The $185M EXIM facility under the Make More in America initiative, plus a $15M J.P. Morgan revolver, backs a 270,000 sq ft manufacturing campus in West Austin set to come online in Q1 2027. That is industrial policy meeting phased arrays. Chris Trey Pappas III, CRO, is pushing global expansion from Tokyo to Milton Keynes, because demand for resilient comms does not respect borders.
Trousdale Ventures led the Series C, joined by Woven Capital, Janus Henderson Investors, Airbus Ventures, DBJ, MESH, EDBI, and NewSpace Capital. Repeat capital from Airbus Ventures and DBJ tells you this is not a tourist trade. Investors who understand hardware cycles and defense procurement are doubling down. That matters.
The product lineup is where the poetry hides. Element is a fully integrated LEO satellite with a multi-beam phased array baked in. Vireo handles Ka-band payload duties. Nightingale flies single-beam missions. Skylark brings provider-agnostic Ka-band connectivity to air and ground terminals. This is not a parts catalog. It is a communications stack designed to move at software speed while living in hardware reality.
Space Development Agency programs. NASA Starling cross-links hitting TRL 9. LunaNet work tied to Artemis. A national LEO constellation for Taiwan’s space agency. 8 secured SpaceX rideshares to validate on orbit. When your customer list includes defense layers, lunar architecture, and commercial aviation, you are not dabbling. You are building infrastructure.
The lesson for founders is simple and uncomfortable. Vertical integration is hard. Certifications like AS9100D and ISO 9001 do not trend on social feeds. But when you combine deep technical credibility, disciplined manufacturing, and capital partners who understand the mission, you earn the right to scale.
CesiumAstro is not just raising money. It is manufacturing leverage in a world that suddenly remembers why space, supply chains, and secure bandwidth actually matter.
